Renu Skin Clinic are proud to be the only clinic in Tayside to use this method of mole/lesion removal without the need of any cutting into the skin or stitches leaving a scar . Most dermatologists/surgeons still use this old method today. At Renu we are always at the forefront of technology and invest heavily to make sure our patients get the best results with the best outcome and less side effects.
A new technology, 4.0 Mhz radio- wave surgery has put a new spin on scarless nevi removal. Radiowave surgery is quite different from electro- surgery.
Electrosurgery generally occupies a place on the electromagnetic spectrum from 350 Khz to 1.7 Mhz. The lower the Mhz, the more lateral tissue damage produced with tissue incision. In electro surgery, the electrode tip provides the resistance during ablation. The tip heats up and significant heat is tranferred to the target tissue. This heat also affects the surrounding normal tissues, resulting in lateral tissue damage that can produce scarring. Common dermatology electrosurgical ma- chines operate at low frequencies (500 to 750 Khz, about 500,000 cycles per second), and this results in significant lateral tissue damage.
Radiowave surgery operates at a frequency of 4.0 Mhz, which is about 4 million cycles per second.This is the optimum wavelength for preciseness with minimal lateral tissue damage. The reason that radiowave surgery is much more tissue friendly than electrosurgery has to do not only with the 4.0 Mhz wavelength but the fact that the electrode tip does not provide the resistance and hence does not get hot. It is the tissue that provides the resistance. Radiowaves are transferred to tissue through an electrode. Radiowaves cause a process known as intracellular volatiliztion whereby steam is produced in the cells, causing them to rupture. An- other difference between radiowave surgery and electrosurgery is the ground plate. With electrosurgery, it is possible to shock or burn the patient. Radiowave surgery does not employ a ground plate but rather an antenna that gathers the radiowaves and channels them back to the machine. The antenna, which does not need to be in direct contact with the patient, is Teflon coated so it cannot shock or burn the patient.

A no-scar technique for mole removal that’s far superior to traditional excision methods now at Renu Skin Clinic in Dundee. In the past, the only way to remove them was by surgery – cutting the skin. However, moles, warts and other skin lesions can now be removed easily with minimal risk of scarring, using a method known as radio wave surgery.
Mole removal is a very common procedure in my clinic and using the Ellman radiowave technology and has produced virtually scarless results however there is no guarantee of the reduction of a postoperative scar. Repeated treatments may be required as it is better to retreat than to remove too much.
Ellman Radio Frequency
The Ellman Radio Frequency (RF) technology has been in use for over 50 years in a broad range of surgical applications. Ellman RF units are universally considered as the gold standard in radio frequency surgery, and are being continually researched and revised to provide the best in advanced surgical unit.
At 4MHz, thermal tissue alteration is limited to within 20 microns of the surgical site. That is a factor of 100 times less damaging than conventional electrosurgery.
Resulting from the high-precision and low temperature, there is no peripheral tissue charring or scarring, and rapid healing is promoted. Clinical results have shown decreased post-surgical pain and oedema.
Radio-surgery uses the latest in diathermy technology, the Ellman Surgitron , to literally take the mole away until it is smooth with the skin surface. The Ellman can do this and not leave a scar because the radio frequency energy does not spread and damage the surrounding tissue. 7-10 days after the scab is formed, there is a fresh healthy layer of new skin which over time blends into the normal skin color. We can only remove moles that are benign and raised.
What are the benefits of radiowavesurgery?
- Faster healing
- Minimal scarring
- No bleeding
- Reduces post-operative conditions such as trauma, pain, swelling and infection
- Most effective mole lesions removal are made
- No pressure required to make an incision – ie it can be more precise. NO cutting into the skin.
- Blood coagulation whilst removing
- Bacteria free
- Less scarring produced is less than scalpel incisions as there is no cutting
- Safer than using scalpels
- Superior healing, less swelling, bleeding, pain, and infection afterward compared to scalpel incisions
- Can be used to shave back skin lesions so no stitches are required, and no scars are leftSuperior results to scalpel incisions and better cosmetically
Many patients are interested in removing moles or skin tags, particularly if they reside on the face or visible skin areas including the neck. However, the thought of a scar can sometimes be the barrier stopping them from making that step. Renu Skin Clinic are proud to offer a no-scar technique using the latest laser technology to remove moles and skin tags without the need for incisions or stitches.
Why choose Renu Skin Clinic for Radio Wave Surgery mole removal?
- Latest radio wave surgery
- No incision, no stitches, no cutting the skin
- Minimal discomfort
- Multiple moles can be removed
- No time off work required
- Walk in, walk out
The areas are marked with a surgical pen and then the administration of lidocaine 2% with 1:100,000 epinephrine infiltrated subcutaneously around the base of lesion for complete numbness. An antenna device will be placed close to the area we work on to avoid any shock or burn.
After the procedures, lesions are covered with a triple antibiotic ointment. The lesion will undergo re-epitheliali- zation over the next seven days. By 30 days, the lesion is often indistinguish able from surrounding skin.
Dermascope Spot Check
Prior to each removal your mole/s will be checked on a detailed basis using a tool called a dermascope, which enlarges the view of the mole so that our Nurse can take a good look at its features. Dermoscopy is a technique used at Renu Skin Clinic along with a very detailed medical history which will allow us to achieve a better diagnosis. We also make a referral to a dermatologist or GP if we suspect a suspicious lesion.
